The MOAL / MOA are compact, robust and stable tapered amplifier systems, for wavelengths from 650 to 1080nm, at power up to 4W.
Two versions are available. The full-size MOA allows for single or double-stage isolators on the input and output, and free-space or fibre-coupled input and output. The MOAL is a narrower chassis which does not allow for an internally mounted isolator on the input.
Both MOAL and MOA options feature the same wire-cut flexure mounts used in our MSA system for input and output coupling lenses, to provide outstanding passive stability and simple user-replacement of the TA diode if necessary. Using a carefully designed optical system, MOGLabs achieves very high TA coupling efficiency such that the seed input power can be just a few mW, depending on wavelegth and output power.
For MOA and MOAL, the amplified output can be divided into two beams, one free-space and the other free-space or fibre-coupled.
